:SPECIPIC'ATION forming part of Letters Patent No. 306,156, datedOctober 7, 1884.

Application fil ed January 31, 1884. (No model.)

i'b a whom, it may Cancer-n.-

Be it known that I, CHARLES V. HAYs, of Orange, in the county of Essexand State of New Jersey, have invented certain new and usefulImprovements in Elevators, of which the following is a full, clear, andexact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a front elevation of a part of an elevator to which myimprovement has been applied, part being` broken away. Fig. 2 is asectional elevation of the same taken through the line x x, Fig. 1. Fig.3 is a sectional plan view of a part of the same taken through theliney/ y, Fig. 2.

The object of this invention is to promote security in the use ofelevators.

The' invention consists in an elevator constructed with an arin attachedto the well-door to engage with the carriage when the said door is openand prevent said carriage from 1noving up or down before the door isclosed, as will be hereinafter fully described, and pointed out in the.clainis.

A represents the wall of a building. B is a door Opening into theelevatonwell. G is the earriage, and D are the guide-posts upon whichthe carriage O lnoves up and down.

To the lower part of the door B is attached an arni, E, which projectsinward, so as to enter a groove, F, in the edge of the floor of theearriage O when the door is open, so that the said carriage cannot moveeither up or down while the said door is open. WVhen the door B isclosed, the arm E projects into the space between the carriage O and thewall of the elep vator-well, as .shown in Fig. 3, so as to leave the 40carriage O free to move. The arm E may be made forked, to engage withthe upper and lower Sides of the floor of the earriage O, if desiredx;and the said arm E can be applied to the lower part of the door, asshown in the drawings, or to the upper part of the said door,

as may be desired or convenient. XVith this construction theelevatoncarriage will be lock'ed in place when the door is open, andcannot move up or down until the said door is closed, so that it will beilnpossible for the door to be left open when the elevator-carriagemoves away from the floor where the said door may be, and people willthus be prevented from walking through the doorway into the eleva- 5 5tor-well, thinking they are entering the carriage.

Having thus described my invention, what I claim'as new, and desire tosecure by Letters Patent, is-

l. In an elevator, the combination,with the carriage and the well-door,of an arm secured to said door and engaging the carriage when the dooris open and disengaged therefrom when the door is closed, snbstantiallyas herein shown and described.

2. In an elevator, the combination, with the carriage O, provided withthe groove F and the well-door B, of the arm E, secured to the door andworking in the groove of the carriage when the door is open and into thespace between the carriage and wall when the door is closed,substantially as and for the purpose specified.
